Excitonic structure in CsPbBr nanocubes, nanorods and nanoplatelets: the effect of dimensionality
Jose L. Movilla, Josep Planelles, Juan I. Climente
We present a theoretical study comparing the excitonic ground state properties of CsPbBr nanocrystals with different dimensionality: nanorods (quasi-1D), nanoplatelets (quasi-2…
Electronic structure of InP/ZnSe quantum dots: effect of tetrahedral shape, valence band coupling and excitonic interactions
Josep Planelles, Juan I. Climente
The energy levels and optical transitions of tetrahedral core/shell InP/ZnSe quantum dots (QDs) are investigated by means of multi-band kp theory. Despite the $\overline{T}_…
Internal dynamics and dielectric screening of confined multiexciton states
Josep Planelles, Juan I. Climente, Jose L. Movilla
Recent experimental and computational studies suggest that biexcitons (BX) confined in large CsPbBr nanocrystals experience reduced dielectric screening as compared to excitons…
Binding energy of polaronic trions and biexcitons in CsPbBr nanocrystals
Jose L. Movilla, Josep Planelles, Juan I. Climente
The effect of polaron formation on the ground state of excitons, trions and biexcitons confined in CsPbBr nanocrystals is studied in the framework of effective mass Hamiltonian…
